"A Mr. Potter. Seems to me I've read something about him in the papers. He's very rich."

"Mr. Potter!" exclaimed Larry. "The detective must be from the private agency," he added to himself. Then aloud: "Did he recognize Mr. Ret—er I mean the man with the fractured skull?" and he waited anxiously for the nurse's answer.

"He seemed to, but I was called away just then."

"I know how Mr. Potter looks," Larry went on. "He has a moustache, and the man here is smooth-shaven."

"No, the patient has a moustache and a beard now," the nurse replied with a smile. "They grew since he has been in the hospital."

A sudden idea came to Larry. An idea so strange that it startled him. He dared not speak of it. He believed the detective held the same theory.

"I'll call again," he said, thanking the nurse for the information she had given him. "I must see Grace at once," he murmured, as he left the hospital. "Strange I never thought of that. A beard and a moustache! The private detective! I wonder if he recognized Retto? I must hurry. Oh, if this should prove true!"

He hurried to an elevated station and was soon on his way to Grace's house.
